United States Patent 3,326,808 ANTISEPTIC DETERGENT COMPOSITION Melvin M. Noseworthy, Malverne, N.Y., assignor to Chas. Pfizer & Co., Inc., New York, N.Y., a corporation of Delaware No Drawing. Filed Aug. 25, 1965, Ser. No. 482,147 4 Claims. (Cl. 252-106) This application is a continuation-in-part of application S.N. 387,182 filed Aug. 30, 1964, which is now abandoned.

This invention relates to a novel liquid antiseptic detergent composition useful as a skin cleanser. More particularly, it is concerned with compositions of this type which contain a dissolved oil and a dissolved antiseptic in an aqueous detergent media.

In the past, attempts to prepare such useful compositions of this type have failed since both the antseptic or disinfectant agent and the oil are usually both equally insoluble in water or in aqueous detergent solvent media under the standard conditions normally employed. However, in accordance with the teachings of the present invention, these drawbacks of the prior art have now been largely overcome, thus rendering it possible for the first time to prepare a system which will keep the recommended antiseptic levels of such well-known disinfectant agents as hexachlorphene, bithional, fluorophene, p-chloro-mxylenol, and the like, as well as 5% or more of an oil, like a vegetable, animal or a mineral oil, in a clear aqueous detergent solution and keep said resulting composition stable.

In accordance with the present invention, the clear liquid antiseptic detergent composition, which is useful as hand soap or skin cleanser, comprises from between about 0.1% to about 6% by weight of a disinfectant agent, from about 10% to about by weight of a water-soluble organic anionic detergent, from about 2% to about 8% by weight of a super fatting agent selected from the group consisting of synthetic, animal, vegetable and mineral oils, and from about 1% to about 5% by weight of a polyethylene glycol ether derived from higher fatty alcohol of from 10 to 22 carbon atoms wherein the chain length of the said polyethylene glycol ranges from about 1.5 to about 20, and sufiicient water to total 100%, with the resulting composition always being maintained in the pH range of from between about 5.0 to about 8.5. This product, therefore, functions as a clear detergent skin cleanser in solution form (i.e., in the form of a homogeneous emulsion) and may contain one or more of the aforementioned antiseptic or disinfectant agents, as will be more fully hereinafter described, together with a solubilized super fatting agent in conjunction with the other essential additives previously mentioned.

Preferred antiseptics or disinfectant agents for use in this connection include such bacteriostatic agents or bacteriocides, as the case may be, as hexachlorophen, fluorophene, p-chloro-m-xylenol, bithionol, biphenamine hydrochloride, and a synergistic mixture comprising essentially 20% of 5,4'-dibromosalicylanilide and 80% of 3,5,4'-tribromosalicylanilide, although it is clearly understood that the invention is certainly not limited in this respect. The bacteriostatic agent must, however, be preferably within the aforestated concentration range of from between about 0.1% to about 6% based on the total weight of the c0mposition, and this would, of course, include the normally accepted or recommended levels of the individual antiseptics, such as 3% in the case of hexachlorophene, 2% in the case of bithionol, 0.5% in the case of fluorophene and 2% in the case of p-chloro-m-xylenol, for example.

The detergents required for this invention as cleansing agents are all selected from the class of organic anionic detergents having surface-active properties such as the sulfated higher fatty acid soaps like sodium or potassium Patented June 20, 1967 lauryl sulfate, sodium ix-sulfomethyl myristate or triethylammonium or diethanolammonium a-sulfo-methyl myristate, water-soluble salts of higher alkyl aryl sulfonates such as sodium dodecylbenzenesulfonate and sodium laurylbenzenesulfonate or the water-soluble salts of higher alkyl sulfate detergents such as potassium cetyl sulfate and sodium lauryl sulfate or the water-soluble sulfuric acid esters of polyhydric alcohols that have only partially been esterified with higher fatty acids, such as sodium coconut monoglyceride monosulfate, for instance, or the water-soluble salts of sulfated higher fatty acid amides such as sodium lauric monoethanolamide sulfate, etc. The preferred detergent of choice in this connection is the sodium salt of ot-sulfomethyl myristate since it is easily bio-degradable, relatively inexpensive, does not de-fat the skin to any great extent, is non-irritating and non-sensitizing to the touch, and will form excellent soap suds in addition to being a good foam generator. The corresponding triethylammonium and diethanolammonium salts of a-sulfomethyl myristate also serve as excellent alternative for these purposes i.e., as preferred acceptable detergents in this connection. Additionally, various N-acyl ester salts of sarcosine are also useful in this connection such as the sodium, potassium, ammonium and triethanolammonium salts of N-acyl sarcosines wherein the acyl moiety is derived from an aliphatic hydrocarbon carboxylic acid having from ten to eighteen carbon atoms. Illustrative of these type materials are such compounds as sodium N- lauroyl sarcosinate, triethanolammonium N-lauroyl sarcosinate, potassium N-oleoy-l sarcosinate, ammonium N- stearoyl sarcosinate, etc., with the preferred member being the triethanolammonium salt of N-lauroyl sarcosine.

The super fatting agent or emollient is either a vegetable, animal or mineral oil or a synthetic oil, as previously indicated and it must be present within the aforestated concentration range of from about 2% to about 8% by weight. This particular type ingredient is necessary so as to replace the natural skin oils which are lost or, at least, partially removed by the cleansing action of the detergent. Its primary purpose, therefore, is to leave the skin soft and smooth rather than stifl? and chapped. In addition, it also serves to dissolve and maintain the oilsoluble antiseptics in solution, with the branched chain oils being preferred to the straight chain oils for this purpose. Examples of oils which can be used in this connection include water-soluble derivatives of lanolin, various light-white mineral oils, a modified triglyceride of coconut oil, squalene or spinacene, and a commercial mixture of branched chain fatty acid esters derived from synthetic duck preen gland oil, in addition to synthetic oils such as isopropyl linoleate, di-isopropyl adipate and n-decyl oleate, etc.

The last remaining key ingredient in the compositions of this invention, other than water, is a polyethylene glycol ether derived from a lauryl, stearyl or oleyl alcohol, for example, and wherein the chain length of the said polyethylene glycol unit may range from about 1.5 up to about 20. The concentration range for this ingredient, which functions as a solubilizer and/ or emulsifier for the super fattiug agent, is stated to be from about 1% to about 5% by weight, as previously indicated. These particular glycol ethers are necessary in order for complete homogeneity to occur in the aqueous-oil system containing the bacteriostatic agent and the dissolved detergent therein. The preferred ethers for these purposes are the oleyl ethers of polyethylene glycol and particularly those which contain a glycol moiety in the aforestated unit chain length range.

The resulting final composition must also be maintained within the aforestated pH range of from between about 5.0 to about 8.5 in order to avoid any unnecessary irritating action on the surface of the skin. To ensure that the pH be maintained within this range, small amounts (15%) of non-toxic acidic substances may have to be added, such as hydrochloric acid, sulfuric acid, phosphoric acid, citric acid, stearic acid, lactic acid, gluconic acid or potassium acid tartrate, for example. Lactic acid is preferred in these instances, since it is a natural skin acid which will neutralize the soap to a pH of about 5.0-8.5, with the preferred range being pH 5.5-6.5. Additionally, it is also considered to be the most important organic acid naturally influencing the pH of the skin.

Other ingredients or additives and their amounts which the compositions of this invention may contain, although they are not absolutely essential, are a fatty acid alkanolamide (2-5%), a chelating agent (0.02%), a thickener (0.12%), a dye (trace amounts) and a soap .perfume (0.10.5%). The fatty acid alkanol-amide, which serves as a foam booster and stabilizer, can be any standard compound of this type, although caproic acid diethanolamide is preferred since it affords complete clarity in aqueous solutions. However, coconut acid diethanolamides are also equally useful for this purpose, as are various amine oxides such as those of the formula R R R N O where R is an alkyl radical of from ten to sixteen carbon atoms and R and R are either methyl or ethyl radicals. Examples of these latter type compounds include lauryl dimethylamine oxide and cetyl dimethylamine oxide, etc. The chelating agent acts as a color stabilizer and ethylenediamine-tetraacetic acid (EDTA) disodium salt has been found to be extremely useful for this purpose, although any number of standard chelating agents will do the job here. The main idea is to prevent hazing in the product from occurring due to the presence of calcium and magnesium contaminants in the mixture and to protect the phenolic antiseptics from discoloration due to the presence of iron. The thickening agents serve as viscosity builders and include carboxymethylcellulose, methylcellulose, sodium chloride, the polyox resins of the Union Carbide Chemical Co., and so on. The dye, which may be present in trace amounts varying from about 0.002% to 0.005%, is obviously present for coloring purposes. F.D. & C. Blue No. l is preferred since when small amounts of this dye are combined with the natural light yellow color of the soap mixture, a pale-green tint results. However, F.D. & C. Green Dye No. 5 works equally as well for the purposes at hand. The perfume, which provides the pleasant scent, can be any standard acceptable soap .perfume.

In carrying out the process of the present invention to prepare these novel compositions, the constituents are usually mixed together at a temperature below the boiling point of water and slightly above room temperature, i.e., one which lies within the approximate range of from about 35 C. to about 90 C., with the preferred range in practice being from between about 50 C. to about 80 C. Normally, the disinfectant agent is dissolved in the oil phase, if water-insoluble, and the detergent dissolved in the aqueous phase and the two are then mixed together when at at temperature in the aforesaid range. The polyethylene glycol ether is always present in the oil phase, while the chelating agent and the fatty acid alkanolamide are always first placed together in the aqueous phase along with the detergent. The pH adjustment, if need be, is always made before the mixing of the two phases and again, checked afterwards. The dye is usually added to the aqueous phase after the pH adjustment has been made, and the perfume can either be dissolved in the oil phase first or added afterwards, just before the final composition is allowed to cool to room temperature.

Alternatively, it also is possible in preparing a liquid hand soap or skin cleanser to combine all the main ingredients together first and then to heat the mixture to the desired temperature range, with stirring, until complete homogeneity is obtained. The pH adjustment, the dye addition and perfume tailoring can then be made immediately afterwards. In either case, a clear sparkling de- 4 tergent solution or homogeneous emulsion is always obtained, which is both clear and stable to the eye for long periods of time afterwards at various temperatures in the 5-50 C. range.

In summary, therefore, the present invention provides novel liquid antiseptic detergent compositions of the type hereinbefore described, which are useful as liquid hand soaps or skin cleansers. A particularly useful composition of this invention illustrating a preferred embodiment of same is one comprising from between about 0.1% to about 6% by weight of a disinfectant agent, from about 12% to about 20% by weight of the triethanolammonium salt of N-lauroly sarcosine, from about 2% to about 5% by weight of a miner-a1 oil and from about 1% to about 4% by weight of the oleyl ether of polyethylene glycol, and sufficient water to total 100%, with the pH of said mixture being maintained in the range of from about between about .pH 5.5 to about pH 6.5.

This invention is still further illustrated by the following examples, which are not to be construed in any way or manner as imposing limitations upon the scope thereof. On the contrary, it is to be clearly understood that resort may be had to various other embodiments, modifications and equivalents thereof which readily suggest themselves to those skilled in the art without departing from the spirit of the present invention and/or the scope of the appended claims.
